				Hi Flo, 
The answer is yes, provided that the proper port forwarding settings are made on your firewall/router.
There is a topic on portforwarding for macs here:

Hope it helps,

i never had luck with static router ip. i do have airport extreme and i do port forwarding but dude its so annoying with changing router ips. but if i assign manually it never gets me an internet connection.
